Abstract

A carriage suspension system for use with a lift truck having a tractor a mast including a vertical track and a carriage suspended from the track for movement therealong.
The carriage is raised and lowered via chains, one end of each chain being secured via a compressible spring which isolates the carriage from tractor vibrations and oscillations. The track restricts lateral carriage movement.
